EXCAVATING- BUCKET-HEAD.

' tion.

My invention relates to the heads of what re known in the art asorange-peel buckets and consists in making the head of steel plates heldtogether by removable fastenings so that should any parts wear out orbecome broken by use they may be replaced. Heretofore the heads used inthis class of tool has been cast in one piece so that when it has becomeworn or broken the whole piece has to be thrown away and replaced with anew one. Also as my device is made of rolled steel plates it is muchstronger than the heads made of cast metal.

The construction and operation of my improved bucket head will bedescribed hereinafter and illustrated in the accompanying drawings inwhich- Figure 1 is a side view of an orange-peel bucket with my improvedbucket head in place thereon, Fig. 2, a top view of my improved head,Fig. 3, a side view, and Fig. 4, a bottom view thereof.

In the drawings similar reference characters indicate correspondingparts throughout the several views.

In Fig. 1 is shown a bucket of the type to which my improved head,designated A, is adapted. Said head consists of a plate 1 shown witheight sides though it may be circular or of any other preferred shape.Secured to the top of plate 1 are two angular plates 2, spaced apart atequal distances from the median line of the plate, and having a link 3pivotally secured to their middle and in the center of the head A towhich the lifting rope B is secured.

4 indicates uprights secured at one end of the angular plates 2 by meansof bolts 5 secured through offsets 6 on said uprights.

7 indicates rollers journaled in the upper ends of said uprights, and 8other rollers journaled on the bolts 5, said rollers 7 and 8 acting asguides for the closing rope C that runs therebetween and through a hole9 in Specification of Letters Patent.

plate 1. The function of the closing rope O will be made clearhereinafter.

10 indicates four plates having angular bases 11 secured to theunderside of plate 1, said plates 10 having their middle portionsforming the four sides of a broken square as shown in Fig. 4 and withtheir ends 12 extending outwardly parallel to the imaginary linesforming the diagonals of said broken square, said extended ends 12 beingspaced apart to receive the upper ends of the arms D that support thebucket blades E pivotally secured to their lower ends.

F indicates arms secured to the blades E which extend under the centerof head A and are secured to a frame G carrying a sheave H to which issecured the end of closing rope C.

I indicates cams secured to the ends of the shaft h for sheave H and onwhich are secured one end of chains J the other ends being pivotallysecured to bolts 13 secured through angle pieces 141 and two oppositeplates 12.

As stated hereinbefore the head A being made of the separate plates andpieces as described permits removal of any Worn or broken pieces andreplacing them with new pieces so that my invention reduces the cost ofoperation of excavating buckets of the class described and the head isalso, because of its structure, very strong and capable of lifting veryheavy loads.

Having thus described my invention what I claim is-h 1. A bucket headcomprising a plate of rolled steel, rolled steel angle plates on theupper side to which is secured a link for the lifting rope, rolled steelangle plates secured to the under side of the first mentioned plate andhaving their ends spaced apart, and the supporting arms of the bucketjournaled between said angle plates.

2. A bucket head comprising a plate of rolled steel, angle platessecured to the upper side of said plate and spacedv apart on each sideof the median line of the plate, a link secured to the middle of saidangle plates, upright plates secured at one end of said angle plates bymeans of bolts secured through offsets from said uprights and the angleplates aforesaid, rollers journaled between said uprights, rollersjournaled on said bolts between said angle plates, four angle l Intestimony whereof I hereto afliX my plates secured on the underside ofthe Ylirst signature in the presence of two witnesses. 10 mentionedplate having their middle poi*- his tions forming the four sides of abroken JACOB X KAUTH y; square and their ends extending outwardly imark.
